REC AMP 2 OR 3 SEC FLAME FAILURE RESPONSE TIME DYN

R7824 R7847 R7848 R7849 R7851 R7861 R7886 7800 SERIES F/SAMP - Flame Failure Signal Amplifier FEATURES: Rapidly detects flame failure and provides 2 or 3 seconds of high wattage audible and visual warning time. Continuous cycling relay (i.e. flashing alarm), is available (contact factory for details). PLUG-IN CONNECTOR ASSEMBLY - Heat resistant, polycarbonate connector housing. Long life contacts and durable protective relay ensure long life cycle of service.

The R7849 provides two or three sec response time. For G.E. gravity pilot ignition (GPI) systems that require a rapid response in the event of flame failure, signaling a 2- to 3-sec signal output to the pilot valve via the RP2 connector cable, either manually or electrically. It may also be used with high pressure pilot applications. The R7886 is an electro-mechanical fail safe solution for many high pressure (HPII and HPIII) and other gas control burners originally on GPI systems. It will respond faster than any electronic system available today while providing extended

The original Honeywell flame signal amplifier was an instant success when introduced in 1963. The filter unit, base unit and cables made flame signaling easier, more accurate and trouble-free. The latest generation of flame signal amplifiers contains a current-limiting circuit that provides a 2 or 3 second response time to ensure sufficient battery charging before the warning signal is activated. It also has a neoprene grommet that conforms to any sized cord end so customers can determine their own pin placement for safety and convenience.

Honeywell Flame Signal Amplifiers are engineered to provide 2 and 3 second flame signal failures. The units provide enhanced performance and reliability for high performance HVAC applications. Features include a 3-second sealed flame detector, thermal protector, power supply and relay module. The R7849 is specifically designed for field installation in the bottom of unit furnaces. It is ideal for use in radiant floor heating systems such as hydronic floor heating or electric baseboard heating systems.''

The R7851 is a flame signal amplifier with high sensitivity, high gain, low noise, and fast response time. With a wide range of features, the R7851 provides fast, reliable flame detection to allow for quicker response times. The R7851 uses a NPN output signal and also provides simple circuitry for 1-2 family fire applications. This model includes super sensitivity boost circuitry and preamp which allows the R7851 to be used in open loop NOC applications. The universal power supply included with the R7851 accepts voltages as low as 24VAC, making it suitable for fire panel mount applications

35281, 35282, 35283, and 35284 two and three second flame failure signal amplifiers provide a means for an instantaneous warning to be transmitted from a pilot light to the controller in the event of a pilot light or flame failure.

Honeywell 35281 Flame Signal Amplifiers provide increased control over gas, oil and LP motorized equipment used in foundries, chemical plants, refineries, pipe lines, and utilities. The advanced design includes a two or three second flame response time which yields the fastest response time possible while preventing nuisance trips.
